AI Verdict
This 26.3L micro form factor chassis supports M-ATX/ITX motherboards, 360mm AIOs, and 415mm GPUs, making it a compact powerhouse for high-end builds.
This chassis is a strong fit for anyone wanting a small form factor PC that doesn't compromise on high-end hardware. Its 26.3L volume and support for 415mm GPUs and 360mm AIOs mean you can pack serious power into a compact space. The modularity also helps tailor the internal layout to your specific components.
If you need more straightforward cable management or plan to use a 4-slot GPU with bottom fans, look for cases with more depth behind the motherboard tray or larger overall volume.

Pros
- Accommodates GPUs up to 415mm in length, allowing for large, high-performance graphics cards.
- Supports 360mm AIO radiators and up to 10 x 120mm fans for extensive cooling configurations.
- Features a modular design with a relocatable PSU bracket and tool-less removable exterior panels for flexible building and easy access.
- Equipped with steel mesh panels on the sides and top, providing optimal airflow for internal components.
- Offers compatibility with ATX, SFX, and SFX-L power supplies, including ATX PSUs up to 220mm.
Cons
- Limited space for cable management on the back/right side of the case, potentially requiring custom cables for SFX PSUs.
- Does not include any case fans, requiring additional purchases for cooling.
- Installing 25mm thick fans at the bottom limits GPU thickness to 61mm (3-slot), and a bottom radiator can prevent GPU installation.
- CPU cooler installation can be challenging due to tight clearances, as reported by one user.
Dimension Scores
The steel mesh panels on three sides and support for a 360mm AIO and up to 10 x 120mm fans provide excellent thermal potential for a 26.3L case.
Since the case doesn't include fans, noise levels are entirely dependent on user-chosen components, but the mesh design allows for efficient airflow with quiet fans.
Constructed from alloy steel with quality metals, users report top-notch build quality with no defects.
Users frequently complain about limited space for cable routing behind the motherboard tray, making clean management challenging without custom cables.
Best For
- Building a compact, high-performance gaming PC with a large GPU and liquid cooling.
- Users who prioritize a small footprint without sacrificing component compatibility for M-ATX or ITX systems.
- Enthusiasts who enjoy a modular building experience and plan extensive custom cooling setups.
Not Recommended For
- First-time builders looking for a straightforward, pre-configured case with included fans.
- Users who require ample space for cable routing without needing custom solutions.
- Anyone needing to install a 4-slot GPU with bottom-mounted fans or radiators.
Watch Out For
- If you put 25mm thick fans on the bottom, your GPU can't be thicker than 61mm, so forget about those chunky 4-slot cards there.
- Cable management behind the motherboard tray is tight; one user wished for an extra 0.5 to 1 inch of space for cleaner runs.
- Stock SFX PSU cables might be too short to route cleanly, forcing you to consider custom cables for better aesthetics.
- You'll need to buy all your fans separately since the case doesn't come with any, which adds to the total cost.

What Buyers Say
This case is a bit of a paradox: it's tiny at 26.3L but somehow swallows huge components like 415mm GPUs and 360mm AIOs. People love the modularity and the wood/glass aesthetic, but getting everything neatly wired is a real puzzle, especially with standard PSU cables. The lack of included fans means you're starting from scratch on cooling, which is a blessing for customization but an extra cost.
“Man, this case looks sick with the wood, and I can't believe I fit my monster GPU in here, but my cable management looks like a rat's nest because there's just no room in the back!”
Common Praise
- The modular design with removable panels makes building and accessing components much easier.
- Supports a 360mm AIO and up to 10 x 120mm fans, offering serious cooling potential for a small case.
- Accommodates very long graphics cards, up to 415mm, which is rare for this form factor.
- The wood front panel and tempered glass side panel give it a unique and appealing look.
- The steel mesh panels on the sides and top contribute to excellent airflow.
Common Complaints
- Cable management space behind the motherboard is very tight, making it hard to hide wires.
- No case fans are included, so you have to buy all of them separately.
- Using thick fans or a radiator at the bottom can severely limit GPU thickness or prevent its installation.
- Installing CPU coolers can be a fiddly process, with one user reporting multiple attempts to seat it correctly.
Ownership Tips
- You'll quickly realize that SFX PSU cables are often too short for clean routing, making custom cables almost a necessity for aesthetics.
- Even with the mesh panels, the front top of the case can get a bit warm, though CPU and GPU temps generally remain within acceptable ranges (70-80C under load).
- The flexible PSU bracket is a lifesaver for fitting different components, but you have to plan carefully where it goes to avoid conflicts.
- The tool-less panel removal is genuinely convenient for upgrades and cleaning, not just a marketing gimmick.
Frequently Asked Questions
What size motherboards does this case support?
The Lian Li A3-26.3L chassis supports both Micro ATX (M-ATX) and Mini ITX (ITX) motherboards.
Can I install a large graphics card in this case?
Yes, this case accommodates graphics cards up to 415mm in length. However, if you install 25mm thick fans at the bottom, GPU thickness is limited to 61mm.
Does this case come with fans?
No, the Lian Li A3-26.3L chassis does not include any case fans, so you'll need to purchase them separately.
What kind of cooling options does it offer?
It supports a 360mm AIO radiator and up to 10 x 120mm fans, with steel mesh panels on three sides for optimal airflow.
What power supply types are compatible?
The case is compatible with ATX, SFX, and SFX-L power supplies, with a maximum ATX PSU length of 220mm.
Buying Guide
When picking a PC case, especially a small one like this, you're balancing size with component compatibility and cooling. You need to think about what motherboard size you have, how long your graphics card is, and if you want to use liquid cooling. A smaller case means less desk space, but it also means less room for airflow and cable routing if not designed well. This case tries to give you the best of both worlds, but you'll need to be mindful of its limitations.
26.3L Micro Form Factor
This is the case's total volume. For comparison, a typical mid-tower is around 40-50L. 26.3L is compact, meaning it takes up less space on your desk, but it also means internal space is at a premium, requiring careful component selection and build planning.
Supports 360mm AIO
An AIO (All-in-One) liquid cooler is a sealed liquid cooling system for your CPU. A 360mm AIO is a large, high-performance cooler, usually found in bigger cases. Supporting one in a 26.3L case means you can keep even powerful CPUs cool, which is crucial for performance, especially in a compact build.
415mm GPU Support
This refers to the maximum length of the graphics card you can install. 415mm is very long, accommodating almost all high-end graphics cards available. This is a big deal for a small case, as many compact cases force you to use shorter, less powerful GPUs.
M-ATX, ITX Motherboard Compatibility
These are smaller motherboard sizes. ITX is the smallest, M-ATX is slightly larger. This case supports both, giving you flexibility. M-ATX boards offer more expansion slots than ITX, which can be useful for more storage or other add-in cards, while still being smaller than full ATX boards.
Alternatives
If this case doesn't quite fit, look for cases with a larger volume (30L+) for more cable management room, or those explicitly stating support for 4-slot GPUs with bottom fans if that's your priority.
